Moves and natures I got handled, just confused if 5 31 ivs are acceptable or if you have to have 6 on Rocks T-Tar.I don't see why more people don't run rock polish on mega ttar, but maybe I'm missing something.
For lead tar with rocks, I used 3 different ones last gen. Sassy, with Crunch/pursuit/fb/rocks, adamant with the same moves, and a CB adamant one with stone edge/crunch/fireblast/pursuit
Take your pick, imo :]
